Venue: Singapore University of Social Sciences
Minimum number to run: 25 participants
Certificate of Participation is awarded upon 75% attendance for the course

In this 2-day course we will design the flow of a Blockchain powered “Tic Tac Toe” game where, regulated by the Blockchain Consensus System, users can play one against the other, one Blockchain transaction at a time. While having fun, you will gain an understanding that Blockchain is more than a “distributed ledger”; you will also learn about the difference between a “Smart Contract” and a “Smart Transaction,” how the Blockchain Consensus works, and what it can be used for. After this course, each participant should have acquired the conceptual notions to design systems that are able to solve any decentralised and distributed process using Blockchain as a parameterised communication channel between parties.


A. Knowledge and Understanding (Theory Component)

At the end of this course, participants should be able to:

  • Describe the basics of Blockchain Systems (P2P, Cryptography, and Data Management)
  • Explain the key concepts of Blockchain Consensus System:
    - Flow of a Blockchain transaction - Mechanics of the consensus system
    - The need for “proof of something” to validate blocks
    - The difference between a “Smart Contract” and a “Smart Transaction”
  • Discuss why there are Public, Private, Permissionless, and Permissioned Blockchains

B. Key Skills (Practical Component)

At the end of this course, participants should be able to:

  • Design Blockchain Consensus Logics to provide solutions of any kind
  • Outline the structure, logic, and flows of a Blockchain
  • Identify the right type of Blockchain protocol based on the solution to implement
